Let's divide 281011 by 18
The aim is to understand the frequency of 18 in 281011.

Advancing to step 1:
2 divided by 18 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 18

Advancing to step 2:
28 divided by 18 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 18 from 28 to get 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 18

On to step 3:
The number 18 fits into 101 5 times, leaving a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 90 from 101, we get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 18

Moving on to step 4:
The number 18 fits into 110 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 156.0
If we subtract 108 from 110, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 18

Going ahead to step 5:
When dividing 21 by 18, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1561.0
Deduct 18 from 21 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 18

Moving on to step 6:
18 can be fit into 31 1 times, resulting in a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 15611.0
If we take 18 away from 31, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
18 goes into 130 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 15611.7
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
If we divide 40 by 18, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 15611.72
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
18 goes into 40 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 15611.722
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 15611.722, with a leftover of 0.0004.
